POWER couple Beyonce and Jay-Z have reportedly put their plans to have another child on hold amid marriage troubles.

The pair, who already have daughter Blue Ivy, have been plagued by rumours of a possible split and, despite denials from the superstars, RadarOnline claims the Crazy in Love diva has stopped fertility treatments.

An insider said: "Bey's had enough and wants to give her body a break."

The Formation singer, who has been married to Jay, 46, since 2008, is also reportedly frustrated with the state of her relationship with the famous rapper.

"Jay's got Tidal [the music streaming website] alongside a few lawsuits to focus on right now, and Bey's just tired of trying to do this on her own, especially with the problems in their relationship nowhere near fixed," the insider added.

The decision to stop trying for a baby is said to have left the couple "both devastated" as they initially wanted to add to their family.

Bey has other issues despite her marriage at the moment as she is suing a Texas company selling stuff online bearing the name 'Feyonce'.

The singer, one of the world's most famous and influential pop stars, is trying to stop the sale of dozens of shirts, sweaters, tank tops, hoodies and even coffee mugs bearing the name, which she says is too close to her own trademarked name.

In a complaint filed in Manhattan federal court on Tuesday, Bey accused Feyonce Inc and three individuals, all from San Antonio, of "brazenly" selling infringing "Feyonce" merchandise at their website.

Among the items is a $14.95 mug with the phrase "he put a ring on it," which Beyonce said was intended to call to mind the lyrics of Single Ladies.
